Native Instruments has released
SKANNER,
a free synthesizer by Stephan Schmitt.

Stephan Schmitt – the father of REAKTOR, always
brings something new to the table. This time it’s
SKANNER – a powerful REAKTOR synth built on unique
synthesis architecture.

SKANNER ingeniously mixes sampler and synthesizer.
The two oscillators ‘scan’ a sample; at low
frequencies you get the ‘scratch’ sound of the
sample being read back and forth, while at higher
frequencies the dominant force is the oscillators
being shaped by the sample waveform. The resulting
sounds are raw, dirty and highly unpredictable –
from simple sine waves to walls of noise.

Skanner for Reaktor 5 Player and Reaktor 5 (requires
version 5.6.2 or higher) is available as a free
download.
